A and B molecules of 3-acetamido-1-adamantane-
carboxylic acid related by a pseudo-inversion centre. Hydrogen bonds are depicted as dotted lines.
The title compound is an intermediate in the preparation of an unnatural amino acid, 3-amino-1-adamantane carboxyliccarboxylic acid related by a pseudo-inversion centre. Hydrogen bonds are depicted as dotted lines.
acid. It crystallises in a monoclinic space group with two molecules per asymmetric unit, A and B, related by a pseudoinversion centre. The intermolecular O-H···O hydrogen bonds link the symmetry-related molecules into infinite chains of A and B molecules parallel to the [101] direction. The intermolecular N-H···O hydrogen bonds cross-link these two chains whereas adamantyl cages create a hydrophobic surface around them. K. Molčanov, B. Kojic-Prodic, N. Basaric and K.
